Overview
Mediaplus linked DOOH screens with hyper-locally targeted audio ads to reach Wolt’s urban, hard-to-reach target audience twice over at precisely the right moment. The combination of visual stimulus and acoustic reminder made the 2-for-1 burger offer immediately relevant and cut through the sensory overload of everyday life.
Challenge
Reaching urban audiences in a new way
Wolt, the food delivery service, faces a central challenge: how do you reach a digitally savvy, mobile target audience that barely registers advertising any more in its urban environment?
Young city dwellers are constantly on the move, in a flow between appointments and leisure - and routinely block out generic messages.
Our goal: to place Wolt’s 2-for-1 burger offer prominently in the urban lives of the target audience, create situational relevance, and trigger purchase impulses at the right moment. A major challenge in an industry where many delivery providers compete for the same attention.
The core question: how does a message truly stick amidst constant sensory overload?
Solution
Two senses, one message
At Mediaplus, we opted for an innovative cross-media campaign, which intelligently links two strong channels: premium DOOH screens and hyper-locally targeted audio ads. What makes our approach distinctive is the deliberately deployed audio-visual synaesthesia, in which sight and hearing reinforce one another - at precisely the right moment.
Hyper-local precision plays a central role here: first, we placed striking full-motion creatives on selected premium DOOH surfaces at high-footfall locations in Berlin and Hamburg. These digital screens created an initial visual contact with the Wolt two-for-one burger offer among passers-by. Then came the decisive twist: using programmatic hyper-local targeting, we identified people who were in the immediate vicinity of the DOOH screens and addressed them simultaneously with tailored audio ads. The message reached the target audience at exactly the moment when the visual stimulus was still present and they were listening to music on the move.
The result: a highly efficient real-time campaign delivery, which combines visual activation and acoustic recall into a powerful dual touchpoint.

Beeing present in the right moment
“With this campaign, we reached our urban target audience where they move and live. The combination of visual presence on the streets and acoustic recall via audio ads achieved exactly the effect we had hoped for: more people think of Wolt when they are hungry. The 141 per cent increase in purchase intent shows that we struck exactly the right chord.”
